Republican San Diego Mayor Jerry Sanders, who in 2007 changed his mind on same-sex marriage in a tear-filled press conference with his lesbian daughter, will testify in the federal suit to repeal Prop 8 being brought by superstar lawyers Ted Olson and David Boies.

San Diego Mayor Jerry Sanders will be a witness in the upcoming federal court trial over the constitutionality of California’s Proposition 8, according to San Francisco City Attorney Dennis Herrera. Herrera announced Sanders’ participation today at a San Diego fundraiser for Herrera’s reelection. Herrera said he traveled to San Diego last week to meet with Sanders and that Sanders readily agreed to testify in the case, which seeks to overturn the constitutional amendment banning same sex marriage narrowly approved by California voters last year.

The City of San Francisco has been allowed to join the lawsuit, hence Herrera's involvement. In August a judge ruled in favor of Olson and Boies' request to block the ACLU, Lambda Legal, and the National Center for Lesbian Rights from joining the suit after the groups' earlier denouncement of the attempt.

FLASHBACK: Here is Sanders' beautiful 2007 speech. If you haven't seen it, get out a hankie first.
